Centre for Energy Systems



About the Centre

The Centre for Energy Systems (CES) aspires to be the centre of excellence in the learning and development of clean energy technology, electrical power system and green transportation. It supports the diploma courses in our School of Electrical & Electronic Engineering. The main R&D areas of the CES are in renewables application, energy efficiency, microgrids and smart grids, green transportation and environment. The Centre actively seeks collaborations to develop solutions for industry applications.

Capabilities and Technical Services

The centre specialises in energy systems and green transportation. It provides realistic demonstration of emerging technologies and practices in the areas of solar photovoltaic, wind energy, microgrids and smart grids, electrical power systems and green transportation systems.

Project Showcase

The Centre promotes a wide spectrum of projects undertaken by students and staffs. Some of the achievements and past projects are shown below.

4.6kW solar-wind-hybrid stand-alone system

This system, built in 1996 is for research on solar and wind hybrid operation. It is composed of the following: 2.1kW solar PV system, 2.5kW wind generator and energy storage. The system converts both solar and wind energy into electrical energy for electrical appliances in the laboratory or is stored in the battery bank.

19.2kW grid-connected solar photovoltaic system

This system, installed in 1996, is to study the performance of a PV system connected to the power grid. It consists of four 4.8kW mono-crystalline solar PV systems. The systems are connected to a low voltage grid and supply the power to the teaching blocks. The system has been operating successfully since its installation.

48.88kW solar photovoltaic test bed (EDB CERT project)

The test bed consists of two different systems: one with 10 different PV technologies and another with 13 different installations. The main objectives of this EDB project are to study the performance of various PV technologies in the tropical region and to investigate the impact of different installations on the energy yield of PV system in Singapore.

Development Of An Integrated Solar Photovoltaic-thermal (PVT) Module For The Tropics

EDB CERP project, funded by NRF, in collaboration with Grenzone Pte Ltd, Singapore and National University of Singapore (NUS). The project aims to develop new solar PVT collectors to convert solar energy into electrical energy and thermal energy simultaneously and set up a PVT test-bed in Singapore Polytechnic to conduct experiments on the new PVT collectors.

Solar Photovoltaic Data Centre (EDB CERT project)

Singapore Polytechnic has been selected by EDB to set up a PV data centre that is capable of monitoring, collecting, analysing and recording the data of ten solar PV systems located at different sites in Singapore. The data analysis will help designers, installers and users of PV system to understand the performance of PV systems installed at different locations of Singapore.

MicroGrid system

MicroGrid system, a modern concept for a small-scale localized electricity generation and distribution system, has been developed and operated in SP. The system, integrating different energy sources and energy storages, is able to operate in two different modes: "island" mode" and "grid-connected" mode. Research is underway to optimize the control of the micro-grid system and its efficiency for further commercial applications.

LED Lightings

A few new types of high performance power electronic drivers for high power LEDs have been successfully developed and commissioned in industrial environment for area lightings applications. The most notable one being the lighting up of the water features of Terminal 3 of Changi Airport in 2010.

1. DC MicroGrid system for smart grid (EMA)

The project aims to develop an intelligent, modularly designed grid-connnected DC microgrid control system. Such a system will minimize the negative impact of the distributed renewable energy that are generated from solar PVs and wind turbines, thereby enhancing smart grid performance in terms of system efficiency, stability and reliability.

2. Mobile MicroGrid Management System (MOE)

The project aims to develop a standalone mobile power network management system that is capable of integrating multiple small gensets as well as small renewable sources. This is done through power electronics-based converters, resulting in a mobile microgrid power system with high power capacity and energy efficiency.

ST Kinetics Ltd
3. Grid-Connected Compact PV Inverter With Power Quality Control (MOE)

The object of this project is to develop commercial prototypes of solar PV inverter systems with the capabilities of controlling the active and reactive power flow from the grid in order to achieve high-quality load voltage across sensitive loads and reduced total harmonic distortion (THD) of the grid current caused by non-linear loads.


4. Solar PV-Thermal (PVT) collector and system (MOE)

The project aims to design and develop a novel and compact PVT collector and its smart management system that integrates solar PV and solar thermal systems to achieve improved overall energy efficiency and energy density.
